Opuntia lindheimeri subaramata was described as a stand-alone taxon (O. subaramata) by Griffiths. It is the same as O. engelmannii subaramata described by Weinger (Cacti of Texas, 1988). O. lindheimeri subaramata intergrades with regular O. lindheimeri, but it is a distinct variety that occurs mostly at the western limits of the O. lindheimeri range. The cladodes are fleshier, thicker, “heavier seeming” and “denser appearing” than the cladodes of typical O. lindheimeri. O. lindheimeri subaramata plants make thicker shrubs than the parent taxon. The plants may be shorter than the parent variety, but they can get large. The few spines are yellow but may be flat. They may grade to true dark brown without red (even nearly black) at the base, a characteristic that is unusual for O. lindheimeri. O. lindheimeri subaramata areoles may have few glochids or may have many glochids. The authors have observed plants near Amistad National Recreation Area, near Eagle Pass, TX; near Del Rio, TX; in the McKittrick hills west of Carlsbad, NM; and on the Edwards Plateau of Texas. It may occur north to the Lubbock, TX area. O. lindheimeri subaramata may be hexaploid like the parent taxon, but at least one report suggests that it is tetraploid.
